Description

Technical Field

[0001] The invention relates to the technical field of shield segments, and in particular to a shield segment production mould. Background Art

[0002] Shield segments are precast concrete components used in underground tunnel construction. They are assembly components for shield construction and the innermost barrier of the tunnel. During the tunneling process, the shield machine uses a hydraulic system to assemble the precast segments into rings to form a permanent support structure for the tunnel. Shield segments are usually arc-shaped and have different sizes and shapes to accommodate tunnels of different diameters. During the production process of shield segments, molds are required to produce a large number of shield segments and then transport them to the construction site.

[0003] In the existing patent CN206158755U, a shield segment production mold is disclosed, which solves the problem of inconvenient mold cleaning and grease filling during the segment production process. The utility model includes a base trolley and a bottom mold, the columns at both ends of the base trolley are hingedly connected to the top mold, the bottom mold is fixedly connected to the chassis trolley, the lower part of the end mold is connected to the bottom mold by a hinge, the end mold is connected to the side mold by bolts, and the side mold is connected to the top mold by bolts. In this application, the top pipe is flipped open and closed, the side mold is opened and closed by translation, and the end mold is opened and closed by hinges. It is easy to open the inside of the mold for cleaning and grease filling, which is conducive to ensuring the accuracy of the mold.

[0004] In the above structure, the side mold and the top mold can be demolded. However, in the process of demolding the shield segment, the side mold and the top mold exist independently, and the side mold and the top mold are removed independently step by step. The side mold and the top mold cannot be removed synchronously, and it is difficult to achieve the effect of rapid demolding, which reduces the demolding efficiency. At the same time, it is impossible to provide friction, which causes separation between the mold and the shield segment, resulting in adhesion between the mold and the shield segment during demolding, which is easy to damage the shield segment and affect the quality of the product.

[0016] The beneficial effects of the present invention are as follows:

[0017] The present invention pours concrete between the arc-shaped lower mold base, the side mold assembly and the top mold assembly to form an arc-shaped shield segment product. When the mold is to be removed, the adjustment assembly is used to connect the transmission assembly and separate the transmission assembly, so that the connection assembly is separated from the drive assembly and the top mold assembly, and the lifting assembly is started to slowly generate an upward or downward force trend, so that the lifting assembly applies a trend force back and forth up and down, but the lifting assembly does not move, forcing the side mold assembly and the shield segment product to form friction back and forth, and at the same time, under the action of the transmission assembly, the trend force is transmitted to the clamping assembly, and the transmission force of the clamping assembly is transmitted to the clamping assembly.

Since the side of the shield segment product is separated from the side mold assembly, and the top surface of the shield segment product is separated from the top mold assembly Separation, the lifting assembly drives the side mold assembly to move upward, and the side mold assembly is separated from the side of the shield segment product to achieve the effect of side demoulding. At the same time, the lifting assembly drives the adjustment assembly to move, forcing the transmission assembly to rotate, and the transmission assembly forces the top mold assembly to rotate, forcing the top mold assembly to separate from the top surface of the shield segment product to achieve the effect of top demoulding; when the demoulding is completed, start the side mold assembly to make the side mold assembly away from the side of the shield segment, and at the same time start the driving assembly, so that the driving assembly drives the connecting assembly to rotate, and the connecting assembly drives the top mold assembly to deflect at an angle, so that the top mold assembly is located in a reasonable position. The hoisting equipment can pick up the product smoothly and avoid the top mold assembly and the side mold assembly from obstructing the hoisting equipment. In summary, a shield segment production mold of the present application can provide friction to the side and top surfaces of the shield segment product before demolding, so that the shield segment product is separated from the side mold assembly and the top mold assembly, avoiding the adhesion of the shield segment product to the side mold assembly and the top mold assembly during demolding, which is beneficial to the protection of the shield segment product and improves the quality of the product. After separation, the side mold assembly and the top mold assembly can be demolded synchronously to achieve the purpose of rapid demolding, thereby improving the demolding efficiency and improving the production efficiency of the company's shield segment products.

The bearing on the connecting plate 1102 is connected to a connecting gear 1103 that meshes with the driving gear 1002 and the rotating gear 505.

[0044] Working principle: Concrete is poured between the arc-shaped lower mold base 2, the side mold body 403 and the top mold body 504 through the opening of the top mold body 504 to form an arc-shaped shield segment product;

[0045] When the mold is to be removed, the adjusting motor 701 is started, and the output shaft of the adjusting motor 701 rotates to drive the threaded rod 702 to rotate. Under the guidance of the supporting cross bar 302, the threaded rod 702 drives the supporting block 703 to move, and the supporting block 703 drives the connecting plate 704 to move, so that the connecting plate 704 drives the transmission spur rack 802 to mesh with the transmission gear 801, and at the same time, the connecting plate 704 drives the transmission spur rack 902 to separate from the transmission gear 901;

[0046] Start the electric push rod 1101, forcing the output end of the electric push rod 1101 to drive the connecting plate 1102 to move, so that the connecting plate 1102 drives the connecting gear 1103 away from the driving gear 1002 and the rotating gear 505, until the driving gear 1002 is separated from the connecting gear 1103, and the rotating gear 505 is separated from the connecting gear 1103;

[0047] The hydraulic lifting rod 301 is started, so that the output end of the hydraulic lifting rod 301 drives the supporting cross bar 302 and the reinforcing rod 303 to move, so that the hydraulic lifting rod 301 generates an upward or downward force tendency, so that the hydraulic lifting rod 301 applies a tendency force back and forth. At this time, the hydraulic lifting rod 301 does not move, and the supporting cross bar 302 generates an upward or downward force tendency back and forth, so that the sliding block 402 drives the side mold body 403 to exert an upward or downward force tendency back and forth, so that the side mold body 403 and the side of the shield segment product form friction back and forth;

[0048] At the same time, the trend force acts on the support block 703 and the connecting plate 704, so that the transmission spur rack 802 drives the transmission gear 801 to generate a trend force, which acts on the rotating rod 603 through the transmission gear 801. Since the concave block 602 and the convex block 604 are engaged at this time, the rotating rod 603 acts on the convex block 604 and the concave block 602, so that the concave block 602 drives the connecting block 601 to generate a trend force, so that the top mold body 504 and the top surface of the shield segment product form friction back and forth;

Since the side of the shield segment product is separated from the side mold body 403, and the top surface of the shield segment product is separated from the top mold body 504, the hydraulic lifting rod 301 drives the side mold body 403 to move upward, and the side mold body 403 is separated from the side of the shield segment product, achieving the effect of side demoulding; at the same time, the hydraulic lifting rod 301 drives the support cross bar 302 to move, and the support cross bar 302 drives the support block 703 The connecting plate 704 moves upward, and the connecting plate 704 drives the transmission spur rack 902 to move upward, so that the transmission spur rack 902 drives the transmission gear 901 to turn outward, so that the transmission gear 901 drives the rotating rod 501 to rotate, and the rotating rod 501 drives the rotating plate 502 to rotate. Under the action of the shaft rod 503, the rotating plate 502 drives the top mold body 504 to turn over and rotate, so that the top mold body 504 is separated from the top surface of the shield segment product, achieving the effect of demoulding the top;

[0051] When the demolding is completed, the position of the top mold body 504 and the side mold body 403 is adjusted, and the hydraulic push rod 401 is started, so that the output end of the hydraulic push rod 401 drives the sliding block 402 to move, so that the sliding block 402 drives the side mold body 403 to move away from the side of the shield segment product, and at the same time, the driving motor 1001 is started, and the output shaft of the driving motor 1001 rotates to drive the active gear 1002 to rotate, and the active gear 1002 rotates to drive the connecting gear 1103 to rotate, and the connecting gear 1103 rotates to drive the rotating gear 505 to rotate, and the rotating gear 505 rotates to drive the shaft 503 to rotate, and the shaft 503 rotates to drive the top mold body 504 to rotate at an angle, until the angle of the top mold body 504 is deflected to a reasonable position, so that the lifting equipment can smoothly pick up the product, and avoid the top mold body 504 and the side mold body 403 from hindering the lifting equipment from picking up the product.

[0052] The setting of the lifting component 3 can provide a trending force, thereby providing friction on the side and top surfaces of the shield segment product, and continuously moving back and forth separates the product from the side mold body 403 and the top mold body 504, and at the same time can provide an upward movement force to achieve synchronous demolding of the side mold body 403 and the top mold body 504, thereby achieving the purpose of rapid demolding, thereby improving the demolding efficiency; the setting of the side mold component 4 cooperates with the arc-shaped lower mold base 2 and the top mold component 5 to achieve the casting of the product, and at the same time, after the demolding is completed, the side mold body 403 can be kept away from the side of the product, so that when taking the product, the collision between the product and the side mold body 403 can be avoided, which is conducive to the smooth picking up of the product by the lifting equipment; the setting of the top mold component 5 can cooperate with the arc-shaped lower mold base 2 and the top mold component 5 to achieve the pouring of the product.
